davidarn, it is important to us that you have access to your contacts and I'd be happy to help. Let's take a closer look at the phone to review options on how to locate these unknown phone numbers.
Just for clarification, have you backed the phone up at any point in time? Our back up assistant http://vz.to/2hk8Ira feature is typically utilized with this make/model of phone. Have you attempted to power the phone off and back on since the update? Have any of the contacts duplicated? Please provide a few additional details and we will be ready to continue helping.
